As those of you who follow me on Twitter can’t have failed to notice, last night I briefly appeared on the first episode of the second series of Michael Portillo’s Great Continental Railway Journeys, which followed Mr Portillo from Madrid, via Seville, Cordoba, Jerez and Ronda, to Gibraltar. My segment, filmed in Madrid last May, looked at the anarchist attack on the wedding procession of Spain’s King Alfonso XIII and his British bride, Queen Victoria’s grand-daughter Princess Ena. You can see us above, consulting Mr Portillo’s trusty Bradshaw’s Continental Railway Guide alongside the memorial to the victims of the anarchist bomb, which is in a little square at the bottom of Madrid’s Calle Mayor, opposite Casa Ciriaco, whose proprietor appeared in the programme with his rather grim photograph of the bomb’s aftermath.

If you’d like to know more about the incident, and a recent Swiss novel that provided an … um … unusual take on it, have a read of this blog I wrote back in 2011.

And if for some unaccountable reason you missed the original broadcast, viewers in the UK can catch up on the BBC iPlayer (you have until 8:59PM on Sunday, 8 December, when it will vanish in a puff! of smoke and you will have to resort to buying the no doubt very reasonably-priced DVD).
